Hi i have installed a GTX970 and a R9 390, i want to know how can i specify wich software will be running on the GTX and wich one on the R9.
I know that a windows update can do this but i don't want to update again my windows i have tweaked it like i want and it wasn't easy lol i hope you understand me

Hi sorry for my late reply, i don't really understand what you said but with the nvidia panel i can see wich application is using the 970 right now so maybe you talk about it i don't know
but my main question is to specify before the launch of an application wich graphic card will use wich gpu, i tried with the radeon software but it launch with the nvidia.
The only solution i found is to plug my screen in the R9 and reboot and then it will execute all the application on the R9. But it need to reboot
